I presume you mean open, "out" homosexuals? I can't imagine they're spending much time prying into people's lives outside of work...

It's a christian private school and it is in the rule book. If they discover a child is homosexual they will be kicked out of the school. The rules in this school are very strict. My kids aren't even allowed to attend rock concerts according to school rules.
Excuse me for butting in on this, but my kids are in a small Christian school. We know all the teachers and their spouses and children well. We all also know the other families who send their children there as well. It is a very close community. No homosexuals here! It IS possible to find a good school where the students are taught all sex outside of a traditional marriage is wrong.
